MARKING -ilrAcHINE` .Application led September 16, 1918. .Serial No. 254,227.

To all whom it may concern.'

Be it knowny that we, EDWIN YV. SMITH and DEANE A. CABOT, citizens of the United States, residing at Beverly, .in the county of Essex and State of Massachusetts, have invented certain Improvements in Marking Machines, of which the following description, in connection with the accompanying drawings', is a specifica-tion7 like-reference characters on the ydraw-ings indicating like parts in the several figures.

This inventionl relates to marking machines, an-d more .especially does it concern machines in which the work is impressed in color'- by interposing between it and a die a marking medium, as a pigment or metallic leaf.

In such apparatus the color, medium is often supplied in strip form, the pigment being upon a carrier ribbon of paper. As the die or impression member is heated, and as the strip often passes in its travel from the supply reel to the feed mechanism directly over the die or in close proximity to it-as from aposition upon the frame beneath the die-carrying arm, above the die l and back between it and the opposite impression member or Work support-the ribbon becomes so hot as to cause a separation of the i pigment, spoiling the impression. This we avoid by locating the supply device vand feeding mechanism at opposite sides of the impression members, as shown, one being mounted on the forwardly extending frame arm and the' other between the impression members and saidarm. T Dreferably the supply device is movable-with the marking head, the feeding mechanism being mounted on the frame. Since the travel of the supply device with the head tends -to produce an objectionable slack in the strip, there is hereins'hown a take-upr device movable with the supply device. To hold the strip normally clear of the die and yet pervmit it to be brought into contact therewith for the impression and afterward separated therefrom, there is movably mounted on the head a yieldable guide over which the strip passes. In the illustrated embodiment of the invention a conveniently separable casing is -shown attached tothe marking'head lin which casing the Y,device and supply device, take-up i gui-de are mounted. t I n marking machines .employing a coldr strip, it has been customary,after the impressions, to .accumulate 'thevstrip loosely in a receptacle from which it was'gathered at intervals, .In some instances, as` when metallic pigment or leafis used, thisA waste strip has considerable value for the purpose of reclaiming the metal, and it is. inconvenient to handle in itsv loose form. For

nism. The receiving roll is shown as mounted upon a spindle and formed in collapsible sections, so that when, with the accumulated strip, it is taken lfrom the spindle, its diameter will decrease and it may be slipped from thecoil of'strip materialv and returned to the machine for another winding.

In a strip-supplied marking 'machine it is desirable to be able to vary the amount the strip of marking medium is advanced for each impression. An object of the inven- -tion is to increase the range of this variation. For this purpose a lever 'is provided between the feed mechanism and the member from which it is driven, there being connections from the lever to the driving meinber and to the feeding mechanism, one of said connections being movable along the lever. Herein the non-adjustable connection appears as joinedto the lever between the extremesl of movement of the associated connection. This arrangement results in a coinpound system in which the effect of one leverage may be added to or subtracted from that oi another.

ing member and feeding means with a vari# able connection its end opposite that united to the lever. y

nlhese and other objects are attained by a machine one arrangement ot which is illustrated in the accompanying drawings, in which lFig. l is a side elevation ot a marking machine disclosing our invention;

The trame ot' the machine includes a base l0 having an upwardly and forwardly eX- tending arm 12'. Located at the forward end ot this arm and vertically movable in ways is a head 14 operated by a lever 16 tulcrumed in the arm. rlhe lever is coni nected at its rear extremity by a link 18 and a pin 20 projecting trom one side of the lower end ot the link to a cam 22 carried by a power-driven shaft 24C journaled in the base. itt the bottom ot the head is mounted a die block 26, havingextending transversely through it an opening 28 for a source ot heat, as an electric unit, and an opening 30 to receive a thermometer tor indicating the degree otl temperature imparted to the block by the unit. rlhe under tace ot the head has clamped to it an impression member' in the torni oi' a die B2 bearing the characters or design which is to be impressed upon the work. This die is held in dovetail ways furnished between a fixed abutment 34 at the front of the blockand a movable abutment 'in the form of a slide 36 traveling in dovetail ways 38 extending trom front to rear of the block. lt has been a common practice to urge the movable abutment toward the iXed. abutment bly springs tor the purpose of clamping the die` but in the presence of such heat as is employed in machines of the character herein described, these springs tend to lose their temper and become inetlective.- ille thereto turn in bearinos onthe block. This screw 'has at one extremity outside the block a squared head elet, or other means by which lit may be rotated. ln the slot, threaded upon the screw a2, is guided a. block a6 trom the bottom ot' which depends a pin orj projection t8 lying within a slot. 50 in. the movable die-holding abutment 36. The slot 50 is inclined with relation to the sides of the block 26 and the direction otl movement ot the slide 36, preferably at a'n angle of a5". When the screw 42 is turned, torcing the pin 48 against the wall of the slot 50, a component ot the thrust moves the slide toward and from the fixed abutment to clamp the die in the way 34E or to release it therefrom. lt is to be observed that the head 44C by which the screw is turned is at the side ot the die block, where it may be readily reached by the operator, it being entirely clear of the strip ot marking medium, so that the adj ust-ment may be edected without danger of injuring thedelicate material. j Carried upon the base and alined with the diey is an opposite impression member, furnished by a table or work-support 52. rlhe table may be removably mounted, as by `ways 54, upon a head 56, so that supports ot dillerent forms and sizes may be applied to' the machine. From the under side ot the head projects a spindle 58 having at its lower end a ball 60 seated in a hardened socket 62. lhe socket is mounted in acasf ing consisting of a sleeve 64C across which extends a supportingpartition 66 for the socket. 'l`he table and its appendages may be retained in place in the casing by a pin 68 passing laterally through the casing walls and through an opening in the ball. About ithe spindle, contacting with it and the surrounding wall-of the casing, is an annular spring 70, shown as formed of sheet metal and with separated armswhich at their. centers are connected by a band pinned to the spindle and at their outer ends rest against `the casing. This spring normally maintains the spindle in a vertical position and the Ywork-support-ing surface horizontal. The casing is received by a cylindrical recess or bore 72 in the base, so that the worksupporting structure is removable as a unit.

\The lateral yield ot the table .about the adjust itself to the angle of the die surfacev and to irregularities in the work.

At the front of the impression head 14 is carried a' supporting casing 74, having an upper partly cylindrical portion 76 and a downwardly narrowed, extension 7 8. Near the bottom of the extension are' horizontal arms 80, in which are slots to receive pins 82v projecting from the sides of the lower extremity of the head and screws 84 threaded into the head, these holding the casing firmly in place yet allowing it to be easily removed when desired. Situated in the axis of the portion 76 of the casing is a spindle 86 to receive a supply roll 88 ofa marking medium or color 'ribbon (zo-operating with the die to mark the work. The supply roll is contact with a guide bar 112. This bar isA face of the die.

the table toeffect the impression, the guide retained upon the spindle bya movable head 90, thisv head having aspring-pressed dog 92 engaging any one of a series of circumferential grooves 94 situated at the outer end of the spindle 86. The head may beadjusted by means of the dog to properly contact with supply rolls of different lengths. At the opposite end ofthe roll is a brake member furnished by a fork 96 of spring metal depending from one extremity of a rod 98` passing through an opening in a lug 100 fixed to or integral with the upper edge of the casingportion76. The rod may be moved to bring the member 96 into more or lessfirm engagement with the end of the supply roll by a finger piece 102 and fixed in its chosen position by a set screw 104 threaded through the lug and contacting.

l is drawn off.

From the source of supply the ribbon passes over a take-up member consisting of a rod 106 having at itsopposite ends crank arms 108, 108 mounted to turn in side walls of the casing 74. `Gooperating withy one of the arms is` a spring 110 exerting its tension to move'the horizontal portion 106 of the rod outwardly toward the front of 'the casing. 4 It is thus pressed against the strip, holding taut anyV slack therein.. Leaving the take-up member, the ribbon runs through the portion 78 of the casing into carried upon vertical arms 114 operating in sockets 116 depending from the bottom of the casing, there being in each socket be-y tween its upper extremity and a shoulder on the corresponding arm a spring 118 acty ing to force the bar downwardly until its lower edge lies below the impression sur- As the die is moved toward bar across which the marking ribbon 'extends bears upon the surface of the work winding roll 130.

and yields, thus laying the ribbon upon the work in advance of the die ready to receive the impression. Then when the head rises ping the ribbon from thedie surface.

Locatedupon the base of the machine, bei tween the table 52 and the -arm 12, is a sep arableframe section 120 upon which is mounted feed and winding mechanism 122 for the ribbon. In opposite upwardly extending walls 124, 124 of this frame section are journaled upper1 and lower feed rolls 126 and 128, respectively, and a receiving or` Rotatable upon a stud 132 projecting from the outer face ofy one of the walls 1'24 is a gear 134 arranged to turn through successive steps under the inluence of a one-way clutch 135 of `any suitable'type. and an actuating arm'136. The gear 134 is connected by an idler 138 lwith a gear 140 fixed upon the shaft of `feed roll 128, while upon the shaft of feed roll 126 is a pinion 142 meshing with the gear 140. This gearing turns the feed rolls in opposite directions, as indicated bythe arrows in Fig. 1 of the drawings, and when the ribbon from the supply roll is introduced between them,`draws therefrom successive portions for presentation between the die and work. The winding roll is rotated by a vgear 144, as shown by the arrow, meshing directly with the gear 134 and serves to receive in a' coil the used ribbon, as will later more clearly appear. The arm 136 isoperated from the cam shaft 24 by a compound lever system. Fulcrumed at 146 o n the aim 12 of the frame is a lever 148 joined near its center by a link 150 to a lever 152 .fulcrumed in the base of the frame. A roll 154 upon the lever 152 co-operates with a cam 156 fast upon the'shaft 24. The lever 148 is shown as slotted longitudinally, and passing through this slot with a bearing atits outer end is a screw 158, which maybe turned by a head 160. Threaded upon the screw and movable in the slot is a block 162, to which and to the arm -136 is articulated a link 164. Thus the motion istransmitted from the driving shaft tov the feeding and winding mechanism through a doublelever system, and as the link 150 is connected to the lever 148 between the-opposite'extremes of adjustment of the block '162 the effect of one lever may be caused to diminish or` increase that of the other. By this means a relatively bon is yf ed by the rolls 126, 128.

by moving 'the block 162 along the lever 148 by the screw 158 or byshifting the connection of the link 164 to different openings 165 in the arm 136, or both.

The ribbon when fed between the rolls 126 and 128 is prevented from curling over or sticking upon the upper roll by fingers 166 'projecting from a carrier bar into grooves 168 in said upper roll. llt is then led to the winding roll, which surrounds a spindle 170 rotatable in vone of the walls 124 by the gear 144. About the spindle is a sleeve 172having at its end toward the gea-r a flange 174 pressed toward a flange 176 on `the spindle by aspring 178Ainterposed between the opposite end of the sleeve and a nut 180 threaded upon the spindle. Be tween the flanges 174 andg176 we prefer to place a friction washer 182 of leather or other suitable material. rl`his arrangement causes the sleeve and winding roll carried thereby to rotate with the spindle under the inHuence of the gearing, yet to slip if its rate of rotation is greater than that at which the rib- The gear ing is so proportioned that the rate of advance of the ribbon by the winding roll and b-y the feed rolls is the same for the minimumdiameter of ribbon uponthe winding roll, the latter slipping as the coil accumulates. rl`he winding roll is in sections 184, 184, pivoted at 186 and drawn into firm enf gagement with the outer surface of 'the sleeve 172 by a pair of helical springs 188, 188. rthese springs are situated in alined openings in the roll sections at the side of the spindle 170 opposite the pivot and have their ends xed to said sections. rl`he space between the open ends' of the pivoted sections is such, that when the roll is removed from the sleeve the sections are drawn by the springs towardy one another, thus collapsing to permit the roll to be slipped from the accumulated coil of used ribbon. lt may rthen be returned to the sleeve for the purpose of winding another coil. The end of the ribbon may be attached to the roll in either of two recesses 190, 190 extending longitudinally of the sections near their circumferential centers and opening through the surface, The end portions of the slot openings are contracted at 192, 192. Either slot may receive a rod 194, of such diameter. as topermit it to 4pass through the opening in the surface of a section. The rod has end por tions 196, 196 attened at opposite sides, so that when these flattened portions: are alined with the-contracted openings 192 they may enter them and be locked therein to secure the rod in the slot by turning the portions 196 at an angle to the openings. `With the rod removed from the slot the endy of the ribbon to bev coiled is laid vin it, the rod forced down through the surface opening and then rotated to secure the rod and ribbon against displacement. v'When the roll 1s remoyed from the sleeve the end of the ribbon may be freed from it by withdrawing thefrod longitudinally through the end of the `slot by grasping an angular end portion 198.

lt is sometimes necessary to take a supgly roll of the marking ribbon from the machine vbefore it is all used, and it is desirable to the bite of the feed rolls and the supply roll..

To avoid this, the bearings 200 of the roll lfiith the rolls 126,

126 are shown as movable in ways in the wall 124. rlFhese bearings have `upward extensions 202, in -which extensions are openings to receive eccentrics 204 fast upon a shaft 206 journaled 'in the walls 124. By -means of a finger piece 208 upon the shaft 206 the latter may be turned with the eccentrics, thus raising the bearings 200 and separating` the roll 126 from its com-` panion roll. This frees the ribbon, so that it may be drawn back to enable the operator to tear off the strip at a point which will give the length necessary upon restoration to the machine to fully reach to the winding roll.

11i-using the machine, a` roll of the desired marking medium is placed upon the spindle 86 with the head 90 and fork 96 adjusted to hold.it in theproper position and 4against too free rotation. rThe end of the ribbon is passed over the take-up rod 106, beneath the guide bar 112, across the face of thedie and between the feed rolls 126, 128. rlhen the end is introduced into one of the slots 1.90 and there secured by the rod 194. The com-- poundl lever system interposed between the cam shaft and the feeding and winding mechanism is adjusted to cause the feed rolls, uponeach` rotation of the cam shaft, to draw off from the supply roll a fresh length of the ribbon vsufficient to cover the impression face of the die. rThe operator lays the work to be marked uplon the table 52 and starts the machine by applying power through a clutch mechanism not shown. The head descends, carrying the die toward the work, and, as the distance between the supply roll and feed rolls is tension of its springs, and the die following the guide into contact with the ribbon, produces an impression, the table yielding if necessary upon itsv universal support to compensate for irregularities in the surface of the die orthe thicknessof the work. The head rising, the ribbon is carried away from the die face by the downward movement of the guide bar acted upon by its springs. When the head reaches its highest position, the feed rolls are rotated'to draw from the supply rolla fresh length of the ribbon, this bringing. the, take-up member to the position shown in full lines in Fig.` 1. At the same time the `used material is wound upon the receivingl roll 130 for removal andreclamation when desired. Having thus described our invention, we claim as new and desire to secure by United States LettersPatent: l l.
